Question Mode Matching Question Match the following description with the appropriate programming language generation. 1GL 1GL dr
erastovalidia [21]

Answer:

1GL: Machine language. Represented by a series of 1s and 0s.

2GL: Assembly language. An assembler converts 2GL into machine language.

3GL: High-level programming language. Uses a compiler to convert into machine language.

4GL: Specifically designed for creating database management programs.

5GL: Extremely advanced. Uses statements (scripts) rather than algorithms.

Explanation:

Programming languages started as a series of binary digits (i.e. 0's and 1'). This generation of language is referred to as the first generation.

However, the machine language were difficult to read by human, so mnemonics were created (i.e. assembly language). This language uses symbolic codes such as ADD for addition, etc. This is the second generation

The third generation are the high level languages that uses languages that can be easily understood by human, e.g. + means plus. However, the language must be translated; hence the need for a compiler or interpreter, as the case may be.

The fourth and fifth generations are extensions of the third generation languages. The fourth were created to connect to DBMS while the fifth are more advanced.

Likurg_2 [28]

Answer:

A. Technicians A and B

Explanation:

When we're talking about generic scanners and about all OBD-II codes, in this case, both technician A and B is the correct answer. Because we can scan all OBD-II codes with a generic scan.

But the technician A just says generic tools must be able to read all generic OBD-II codes and technicians B just says generic scan tools must be able to read manufacture OBD-II code, both are correct.
